Question

Find the domain of the function expressed by the formula:

y=1/x −7

Answer 1

ANSWER: All real numbers except 7

Answer 2

it's fraction function so when(x-7) is equal to zero the function will be undefined

to find when x-7 is equal to zero we will have to solve this equation

x-7=0

x=7

so when x is equal to 7 the function is undefined so the domain is all real numbers except 7
